Izihloko mayelana nokuqashelwa kwamagagasi
Esinye isici samagagasi ukujikijela. Ukujikijela kwenzeka lapho igagasi elalihamba ekuqaleni ngenye indlela lingena kwenye indlela. Isibonelo, igagasi lomsindo liqala lihamba emoyeni bese lihlangana nodonga, amanye amagagasi omsindo aboniswa udonga, amanye ajikijelwa udonga. Ukujikijela kusho ukuthi amagagasi omsindo ayamuncwa noma adluliselwe odongeni, kodwa indlela yokujikijela iyashintsha. Ushintsho endleleni yokujikijela kwenzeka ngoba ijubane legagasi lomsindo liyashintsha lapho lingena kwenye indlela ehlukile kunendlela yangaphambilini.
I-engeli ephakathi komsebe wesigameko kanye nowejwayelekile ibizwa ngokuthi i-engeli yokwenzeka, kanti i-engeli ephakathi komsebe wesigameko kanye nowejwayelekile ibizwa ngokuthi i-engeli yokwenzeka.
Uma ijubane legagasi likhuphuka uma lingena endaweni entsha, i-engeli yokugudluza nayo iyanda. Ngokuphambene nalokho, uma ijubane legagasi lehla uma lingena endaweni entsha, khona-ke i-engeli yokugudluza nayo iyancipha.
Isibonelo, igagasi lomsindo lisuka emoyeni liye emanzini, ngakho ijubane legagasi lomsindo liyancipha. Noma amagagasi okuzamazama komhlaba asuka phansi aye emadwaleni, anciphisa ijubane lamagagasi. Ngokuphambene nalokho, ijubane legagasi liyakhula lapho lisuka endaweni exinene kakhulu liye endaweni exinene kakhulu.
Wake wadlala ogwini lolwandle? Uma unaka kakhulu, indlela amagagasi olwandle ahamba ngayo phakathi nolwandle ayihlali iya ogwini lolwandle.
Kodwa njengoba isondela ogwini lolwandle, indlela amagagasi olwandle aqonda ngayo iya ngokuya iqondana nolwandle. Lokhu kwenzeka ngenxa yokuguquguquka kwamagagasi olwandle.
Umthetho Wokuqabula
Ngesikhathi esifanayo, i-wavefront 1 inyakaza ibanga elingu-l 1 = v 1 t kanti i-wavefront 2 inyakaza ibanga elingu-l 2 = v 2 t. Lapho i-v 1 iyijubane legagasi eliphakathi nendawo 1, njengomoya, kanye ne-v 2 , yijubane legagasi eliphakathi nendawo 2, njengamanzi.
U-P uyafana, ngakho-ke womabili amafomula enza kube lula ukwenza okulandelayo:
